Reducing Flow In A Canister?

    I have a cascade 700 on my 37 gallon tank with the spray bar but the flow is still way too strong. Is it possible to reduce the flow on a canister filter somehow?

    You can add a prefilter sponge on the inflow. Does that filter not have the lever to reduce the flow?

    Flow rate can be adjusted with the valves on the hoses. The same
    valves you close to remove the filter for cleaning. You can also re-direct
    the direction of flow from the filter... Sometimes that's all you need.

    Leave the valves open.

    Drill out the holes in the spray bar.

    Rhe flow remains the same, but the problem is the pressure.

    When a given flow is discharged from a smaller opening, it will come out with higher pressure causing more current within the tank.

    Enlarge the opening, pressure decreases and the current does also.

    You could also turn the spraybar so it sprays against a wall, which then disperses the flow.
